I am disassembling my stock rollers to clean them as part of a full rebuild [they have a lot of sludge in them] and want to know if there is a proper way to re-install them. Do you just soak them in run-in oil then drop them in the lifter bores then prime the engine oil system before setting the lash or what?

 

that's what i do, drop them in oil then install, i like to use moly lube on the cam, but on a roller you wouldn't need to

 

Perth,

I know Ede and I both presumed this, but I had to mention it for anyone else reading the post - You did mark the lifters for the correct position on the caamshaft, right? (The lifter from the #1 intake goes back to the #1 intake position, etc.)

 

What if you are replacing the lifters with new ones, instead of reusing the old ones?


I ask because my friend is selling me an LT1 cam with lifters from the LT1 and hardend pushrods. since they are out will I have that problem of which lifter goes into which bore?

 

I know for flat tappet lifters, going back into the same hole is important; but for roller lifters, I was under the impression that it didn't make any difference.

 

Roller lifters can be installed wherever unlike their flat-tappet cousins

 

5-7,

You're probably right. It doesn't matter nearly as much with rollers, but the wear patterns really need to be matched on a flat tappet cam and lifters. Call me ****, but just in case there is some wear between the lobe and roller on the lifter, and that wear isn't perfectly square (since the lifters are retained from rotating), it may be beneficial to put them in the same places. Actually, I'm probably just **** and need an excuse to use the cool little valve train part tray with all the numbers and holes.

For a new installation it really makes no difference and there is no need for anything but clean engine oil as an assembly lube. When reusing old lifters, it would be important to inspect any of them for wear (especially the roller axles) and replace any that revealed problems. If there is no apparent wear, you could probably safely install them anywhere. O.K. - so I AM ****...

 

I don't think your **** Vader.


I think you give very valuable info.

what if I were to use used lifters from an LT1 with the LT1 cam in
my ol'305 TBI?

I am getting an LT1 cam, lifters, harndend pushrods, and a set of
1.52 roller tip rockers TODAY!
